most people will not like these due to the amount the front end will drop...you will bottom out on just about anything/everything. i have them on my car and it will definitely limit where you can take your car. certain driveways, speed bumps, etc. will be a no go. Ride quality is very bouncy...haven't gotten to test them at the strip yet...they seem to transfer weight very well as they should...
the M-5300-Q variant cobra jet springs only lowers the car a bit (mainly brings the rear level with the front). I have a set on my '05 and it measures ~28.5" from floor to top of fender well arch at all four corners. The Q version is cheaper than the R/RA versions too...
I installed the 2013 CJ springs and they stayed on my car for about 1 hour before I took them back off. The car scraped everything!! Even just driving over a dip in the road would scrape in the front with the shocks at full stiff. Maybe it's my TVS making it heavier, but they didn't work for me.
